IntroductionHops is a plant used in the process of brewing beer. Beer has been brewed with hops for hundreds of years as a preservation agent. The compounds in hops responsible for the bitter flavor many people of age experience are isohumulones. Humulone is photosensitive and can change to an isohumulone through a process known as isomerization. The goal of the research is to isolate humulone and see how different conditions will affect the isomerization. Light is a known factor, but there are other factors that can be explored. Temperature can affect isomerization rates along with pH levels of water.
